PROFILE
Chris Kay
Worked on zephyrproject-rtos/trusted-firmware-a, delivering seven features and three bug fixes over four months focused on build system reliability, dependency management, and cross-platform consistency. Developed centralized AArch64 register accessors in C and Assembly, improved linker script handling, and modernized the build process by enforcing POSIX environments and removing legacy Windows logic. Enhanced Python-based tooling with Poetry for dependency management, refactored packaging, and consolidated Dependabot automation to reduce update noise while maintaining security. Addressed CI/CD friction by standardizing build targets and hardening dependency installation, resulting in more robust releases and streamlined maintenance across embedded systems and DevOps workflows.
